Default Health-Care Surrogate Priority in Connecticut

Short answer Connecticut's advance-directive chapter makes the next of kin a source of information about an incapacitated patient's wishes when life support is at issue; it does not turn that consultation list into a general family consent order. An appointed health-care representative has decision authority, and a court-appointed conservator of the person may receive medical-consent authority. A clinician's life-support decision and Probate Court review follow the specific statutory conditions.

At a glance

When the default route opensFor life-support withdrawal, patient is incapacitated and terminal or permanently unconscious; clinician must consider wishes (§ 19a-571(a)). Conservator route requires court appointment (§§ 45a-650(f), 45a-656(a)).
Care or setting covered§ 19a-571(a) governs life-support decisions by attending clinician or licensed facility; court-assigned conservator authority can cover medical or other professional care (§ 45a-656(a)).
Guardian or appointed agentAn operative appointed health-care representative's decision generally precedes a conservator's, subject to § 19a-580e(b)'s exceptions (§§ 19a-580e(b), 45a-650(j)).
Family and partner orderSpouse, adult child, parent, adult sibling, grandparent are 'next of kin' for consultation about life-support wishes; § 19a-571(a) gives them no family voting ladder (§§ 19a-570(10), 19a-571(a)).
Friend or other nonfamily personClinician may consult others to whom patient communicated wishes; court may assign medical-consent authority to a qualified conservator (§§ 19a-571(a), 45a-650(h), 45a-656(a)).
Decision within one class§ 19a-571(a) directs clinician consultation, not a same-class family vote; a conservator acts within individually assigned court powers (§§ 19a-571(a), 45a-650(m)).
Who is available and eligibleConsult representative, next of kin, guardian, conservator and other known speakers if available; clinician makes reasonable effort to notify listed people before life-support removal (§§ 19a-571(a), 19a-580).
Decisions limited or excludedLife-support withdrawal requires best medical judgment, qualifying condition, and consideration of wishes; beneficial treatment continues without terminal or permanent-unconscious finding (§ 19a-571(a)).
No surrogate or disputed authorityProbate Court hears disputes over advance-directive provisions and representative capacity; court may appoint a conservator with limited medical-consent authority (§§ 19a-580c, 45a-650(f), 45a-656(a)).

Requirements one by one

Life-support decisions and consultation

When an incapacitated patient has no living will describing the relevant wishes, § 19a-571(a) directs the attending physician or advanced practice registered nurse to consult the patient's own statements and, if available, a representative, next of kin, guardian or conservator, a designated person, and others known to have heard the patient's wishes. The clinician's life-support decision requires best medical judgment, a terminal or permanent-unconscious finding, and consideration of those wishes. Without such a finding, beneficial treatment, including nutrition and hydration, must continue.

The definition in § 19a-570(10) ranks spouse, adult child, parent, adult sibling, and grandparent as “next of kin.” In § 19a-571(a), that rank identifies people to consult about wishes; the treatment decision remains with the clinician under the conditions above. Under § 19a-580, clinicians also make reasonable efforts to notify the available listed people before life support is withheld or removed.

Court-assigned medical consent

Under § 45a-650(f), the Probate Court may appoint a conservator of the person after the stated clear-and-convincing findings. Under § 45a-656(a), the court may assign authority to consent to medical or other professional care. The conservator's powers are limited to those assigned and must be the least restrictive intervention under § 45a-650(m). Under § 19a-580e(a), the conservator also respects known prior health-care wishes. Sections 19a-580e(b) and 45a-650(j) generally put an appointed health-care representative's proper decisions ahead of a conservator's, subject to their stated exceptions.

What trips people up

A relative's place in the “next of kin” definition does not make that relative a substitute health-care representative under § 19a-571(a). The section asks the clinician to learn the patient's wishes from available people. A family dispute about what the patient said may reach Probate Court under § 19a-580c(a), which applies a clear-and-convincing-evidence standard to communications outside a qualifying document.

Common questions

Does a spouse automatically decide? Section 19a-570(10) places a spouse first among next of kin, but § 19a-571(a) uses next of kin for consultation about life-support wishes. A spouse can have decision authority through a separate appointment or court-assigned role.

What if no representative is available? For the specified life-support decision, § 19a-571(a) describes a clinician's judgment and consultation. For broader medical-consent authority, §§ 45a-650 and 45a-656 describe a court-appointed conservator.
